To all whom it Wtay concern:

Be it known that I, OLIN S. FELLOWS, a citizen of the United States, residing at Middletown, Orange county, and State of New York, have invented certain new and useful Improvements in Means for Removing Superfinous Solder from Sheet-Metal Cans, of which the following is a specification sufficient to enable others skilled in the'art to which the invention appertains to'make'and use the same.

My invention relates to the class of soldersaving apparatus set forth in my Letters Patent Nos. 586,966 and 586,967, dated July 27, 1897, and Nos. 595,704 and 595,705, dated December 21, 1897; and it consists, essentially, in the special construction and arrangement of parts herein set forth and claimed specificallv.

In the accompanying drawings, Figure 1 is a plan of my improved apparatus with covers in place. Fig. 2 is a similar view with covers removed; Fig. 3, a detail view of the adjustable yokebearing, in which the brush is mounted.

Fig. 13 is a sectional view, illustrating the construction and operation of the fluid-pressure nozzle. Fig. 14 is a sectional elevation upon plane of line 14 14, Fig. 1; Fig. 15, a sectional eleva tion upon plane of line 15 15, Fig. 1-, Fig. 16, a sectional elevation-upon plane of line 16 16, Figfl. Fig. 17 is an elevation of the retarding-wheel and its solder-stripper; Fig. 18, a sectional elevation of the same; Fig. 19, a transverse section upon plane of line 19 19, Fig. 17; .Fig. 20, a top view of the adjustable bearing for the retarding-roller shaft. Fig. 21 is a top view, and Fig. 22 a side view, of adjoining portions of the soldering appara- Figs. 8 and dare respec tus and the solder-savin g apparatus, between which is interposed my special arrangement of transferring device.

A is the main supporting-frame of the soldersaving apparatus, made in the form of an elongated base or box, the bottom and sides of which are continuous, so as to constitute a chamber a, which is partly inclosed at top by the table 0., upon which is secured thelextension-chamber A, fitting over the opening in the table a and closed by a cross-plate a. and covers a a a. The end walls of the extension A are formed-with opposed openings or inlet and outlet ports I) b, between and through which the parallel can-supporting rails c c extend, the cans being delivered to said rails from the soldering-machine by an endless belt B or other suitable feed mechanism.

Mounted upon the table 0. within the extension-chamber A and parallel to the rails c c is a cylindrical brush D. The accurate alinement of this brush with relation to the rails o c is of special importance, since an even uniform pressure of the brush upon all the cans passing it on the rails is essential in order to attain the best results. For this reason I mount the journals of the brushshaft 01 in bearings e 6, formed in a yoke E, which is secured adjustably upon the table a. It is obvious that the adjustment of this yoke E with relation .to the rails c 0' may be effected by the employment of various mechanical expedients. In the drawings the bearing-heads are formed with slots 6 e, through which protrude bolts 6" e", engaging with screw-caps 6 e by which the bearing-heads and yoke E as awhole may be clamped to the table. In order to facilitate the delicateadjustment of the yoke E and brush D with accuracy, I prefer to employ a pinion e? and the sides of slots alin the table a, and the engaging pinions e beingattached to arbors rack 6 the latter being formed or let into I e a passing through the bearing-heads of I the yoke, and havinghandles e ,'by which the pinions may be turned upon the racks to slide the yoke and brush back or forth more or less as may be required in actual use. In order to admit of this adjustment of the brush 1 and yoke with relation to the rails c c and at the same time to insure a steady even speed I and pressure, I operate the brush-shaft (Z by means of spiral pinion d, secured to said shaft, and a spiral driving-wheelf upon the power-shaft F, as will be seen clearly by reference to Fig. 14. This form of gearing imparts a positive even speed to the brush, while allowing the pinion d to adapt itself to any reasonable adjustment of the yoke and brush D. It also admits of the inner or receiving end of the brush to be independently forwarded slightly from time to time to com pensate for the comparatively high degree of wear to which said receiving end is subjected in use as compared with the opposite or discharging end of the brush.

The spiral gearf is inclosed in a casing G, consisting of the box-shaped flange a, projecting downward from the table a, and the cupshaped segment g, fitting upon said flange a, the chamber G thus formed constituting a receptacle for the lubricating-oil which is used to insure smoothness in the running of the brush at a high rate of speed, preferably as high as eighteen hundred revolutions per minute. The spiral pinion d is also inclosed by a cap e preferably forming a part of the yoke E, so that the oil thrown off by the pinion is intercepted and returned to the chamber G.

I have devised the means for mounting and running the brush as herein set forth for the express purpose of attaining and maintaining a uniform speed and brush-pressure, so that the cans will be spaced and treated uniformly as they pass under the action of the brush. In this connection it is to be noted that the cans while acted upon by the brush are in contact with the supporting-rails c c', particularly the central rail 0, opposed to the forwarding belt B. I have heretofore opposed a movable retarding-surface to the forwarding-surface, the said retarding-surface traveling in a direction opposite to that of the forwarding-surface. In the present case I use a stationary retarding-surface, over which the cans roll while in contact with the brush. As a result the sides of the cans in immediate contact with the brush move slower than the sides in actual contact with the forwarding-surface B. In other Words, the cans practic-ally roll along the brush, in contradistinction to my old method of attaining a relatively high speed of axial rotation by passing the cans between surfaces traveling in opposite directions. As a consequence the efficiency of the brush is increased, and one of less length. may be used with like result.

Situated a short distance beyond the brush is the vapor-blast I, by means of which steam or other fluid or gas is caused to impinge against the inner edge of the end-plate flange of each can as it passes. I am aware that I have heretofore used steam for blowing 06 excess of solder from the bottoms or end plates of a can, as set forth in my Patents Nos. 595,70at and 595,705, hereinbefore referred to.

The novelty in the present case consists in treating the cans with the vapor-blast immediately after they leave the brush and in using a plurality of diverging nipples or jets, which simultaneously eject steam or other fluid against the inner edge of a can. In the first place the brush is relied upon to remove the excess of solder from the cylindrical sides of the can, including the peripheral flange of the end plate, and this it does thoroughly, excepting that it leaves a slight edge of solder upon the apex or extreme edge ofthe end plate, where it is bent over to receive the edge of the cylindrical body of the can. This sweepingis removed by the vapor-blast,which thus supplements the action of the brush and completes the cleaning operation as a Whole, the blast not only driving olf the excess of solder taken up by the under side of the end plate in the solder-bath, but also removing the ridge or fringe of solder forced to and left upon the extreme edge of the can by the action of the brush, and thus performing the function of a finishing-wiper. The other feature of novelty relating to the vapor-blastnamely, the employment of a plurality of nipples or jets-is designed'not only to have one jet or nipple counterbalance the action of the other, but also to expedite the removal of excess of solder from the bottom of the end plate. Where one or more jets are arranged to cause the steam to impinge upon one side or point of the can only, the pressure of the blast tends constantly to impair the perfect alineinent of the can on the rail. Furthermore, the can has to make a complete revolution upon its axis before it can be forwarded from the blast, thus limiting the speed and capacity of the apparatus as a whole. I obviate these objections by my improved plurality blast 1, arranged centrally with relation to the axis of the can to be treated and formed with two or more diverging nipples t' 2', which are set to eject the steam or other fluid against opposite sides of the exterior of the end plate, as Will be understood by reference to Figs. 13 and 16. In this manner the action of one nipple t' counterbalances the action of the other, and there is no tendency to force the can out of position on the supporting-rails. If two nipples 2' t' are employed, as shown, it is obvious that the whole circumference of the end plate will be treated during one-half a revolution of the can upon its axis, thus admitting of the forwarding of the can in one-half the time heretofore required, and thereby doubling the ca' pacity of the apparatus, provided that the latter is speeded accordingly. t

The cans are held successively over the 1102- zle I by a retarding-wheel J, opposed to the forwarding surface, as in my last patent hereinbefore referred to. This retarding-wheel has a peripheral speed less than the speed of the forwarding-surface, the speed being regulated todischarge the can at a prescribed time after its contact with the retarding- IIO - bearing K, which is adjustable upon the crossplate a with relation to the rail 0 and to the blast-nozzle I. Thus in the drawings the bearing K projects through anelongatedopening a in the cross-plate a on which it is sup ported by its flange 70, the latter being formed with slots 7t 7t for the passage of bolts k 10 screwing into the cross-plate a so that the bearing K may be secured in a prescribed positionand the retarder J adjusted with'accuracy with relation to the path of the cans which it is to intercept and detain temporarily.

In order to keep the retarder J free of solder dislodged by the blast from the nozzle '6, I provide it with a stripper L, which may be attached to any stationary part of the apparatus. I prefer, however, to attach it directly to the bearing K, so that its relation to the retarder J may be maintained whenthe lat ter is adjusted as above stated. This I accomplish by securing the stripper-bladeL to a collar Z, provided with means for clamping,

it to the bearing K, as will be seen by reference to Fig. 19. The pulleyj is rotated by a belt m, passing over the driving-wheel m, secured to the vertical shaft or spindle M,which also carries a pulley m around which passes the forwarding-belt B. The forwarding-belt B also engages the idlers 771 m the latter of which is adjustable upon the bracket or, Figs. 1, 2, and 9, to regulate the tension of said belt B, which receives its power from the pulley n on the vertical shaft N. The latter is driven by a worm f upon the power-shaft F, said worm f engaging with-a spur-gear n, secured to the shaft N. i i

It will be seen that when the covers a a a are in place all the operative parts excepting the belts are inclosed either in the base A or the extension thereof, A, the inlet and exit ports I) and I) being the only openings through which air is admitted freely. By reference to Fig. 11 it will also be seen that the lower portion of the chamber in the base A constitutes a dead-air space of relatively large area,

' sion-chamber A above the table a.

The exhaust-funnel P isconnected with an exhaust-fan Q or any other well-known me chanical expedient for withdrawing the air faces of the joint.

- solder-savi n g apparatus S from the extension-chamberA. As a result air. admitted through the ports b'b is drawn across and around the brush D and vaporblast land into the funnel P, carryingwith it the finer impalpable dust or solder detached from the cans and at the same time creating a partial vacuum or area of low tension inthe chamber 00, into which the heavierparticles of solder are-precipitated from the induced air-current. r

The can-bodies, with the end plates forced thereon, are run through the soldering-machine with their longitudinal axes slightly in-' clined with relation to the horizontal planeof the solder-bath in such manner that the parts.

of thejoint between end plate and can-body to be soldered are successively submerged below the surface of the solder as the can'is rolled'over the solder-bath. In its-passage through the solder-bath the "said joint of the can takes up considerable solder externally; but owing to the nearly-horizontal position of the can when passing over the bath the solder does not always penetrate in sufficient degree between the opposed surfaces of the end-plate flange and the can-body. The joint and'adjoining parts of the can are, however, thor-' wise the means employed by me for remov-- ing the superfluous solder from the'exterior of the can would be ineffective.

of a suficient quantity of the fluid solder into the joint before subjecting the can to the action of my soldersaving mechanism'I turn each can into a vertical or substantially vertical position and maintain itinsuch position while it is being transferred from thesoldering-machine to the solder-saving apparatus, so as to utilize the force of gravityin drawing in the solder around the edge of the joint into and between the opposed internal sur- Obviously this transfer of the can in avertical position from solderingbathto solder-saving mechanism in a sub stantially vertical position may; be accomplished byvarious mechanical expedie'nts, andI do not confine myself to the identical form and construct'ionof parts herein described, although the arrangement shown by way of exemplifica'tion is'simple and practical.

Hencein order to facilitate and insure the penetration Thus in Figs. 21 and 22 the" soldering machine S is formed with dischargerrailss 8,

which-turn the cans successivelyfrom'the inclined position, in which they -havepassed overthe solder-bath,'to a substantially vertical position, in which position they are deposited upon the upper surface of the endless horizontal belt T,- by which they are transferred, still in such upri'ghtposition, to the ways 0 c andforwarding-surface of the It is evident that .by regulating either the length or speed of the transferring-belt T" ment, substantially as set forth.

gravity may thus be utilized in effecting the flow of solder into the can-joint for the length of time requisite to attain the desired result prior to subjecting the can to the action of the devices for removing the superfluous solder from the exterior thereof.
